Zero Waste Masterplan to be reviewed as Singapore recycles less, disposes more

Singapore is set to revisit its ambitious Zero Waste Masterplan, originally launched in 2019, as recent data reveals a stagnation in recycling progress and an increase in waste disposal. The government, led by Senior Minister of State for Sustainability and the Environment Janil Puthucheary, has acknowledged the need for a comprehensive reassessment of the nation's waste management strategy. The review, scheduled for completion by 2027, aims to address the declining recycling rates and explore ways to enhance the sustainability of waste management practices in light of evolving global economic conditions.

As of 2025, Singapore's overall recycling rate stands at 52 percent, falling short of the 70 percent target set for 2030. This marks a notable drop from the 59 percent recorded in 2019, indicating a slowdown in progress toward the nation's zero-waste vision. The domestic recycling rate, which measures the percentage of waste generated by households that is effectively recycled, has decreased from 17 percent to 11 percent during this period. Meanwhile, the non-domestic sector, encompassing commercial and industrial activities, saw a similar decline, dropping from 73 percent to 67 percent. These figures highlight the persistent challenges in achieving consistent and efficient recycling across both residential and business environments.

One of the critical issues identified is the contamination of recyclable materials, particularly within the domestic sector. Blue bins, introduced to facilitate easier sorting of recyclables, have consistently shown contamination levels of approximately 40 percent since 2017. This issue contributes to lower-quality recyclables, which are less valuable in international markets and thus less economically viable for Singapore's export-dependent recycling industry. The National Environment Agency (NEA) reports that the continued challenges include rising collection and transportation costs, along with fluctuating global commodity prices, all of which impact the profitability and feasibility of recycling operations.

In response to these findings, the government has emphasized the importance of revisiting the Zero Waste Masterplan to consider potential adjustments to its objectives and strategies. Particular attention will be given to evaluating the effectiveness of current initiatives, such as the use of blue bins, and exploring alternative methods to improve the quality and volume of recyclables. Additionally, the review will examine the long-term implications of Singapore's reliance on Semakau Landfill, the country's sole landfill site, which is projected to reach full capacity by 2035. Ensuring adequate waste management solutions beyond this date will be a central concern in the review process.

The NEA has also highlighted the need for a more accurate representation of waste management efforts in its reporting mechanisms. Moving forward, the agency plans to refine how annual waste statistics are compiled to better reflect the nation's commitment to reducing, reusing, and recycling waste. This adjustment aims to provide a clearer picture of progress and identify areas requiring improvement.

Despite the challenges, there is evidence of positive change in public behavior. In 2025, each resident in Singapore generated 0.83 kilograms of waste per day, representing a 21 percent decrease from 2015. This reduction underscores a growing awareness among citizens regarding sustainable consumption patterns. However, experts caution that awareness alone is insufficient; converting this knowledge into actionable behaviors remains a crucial step. They advocate for enhanced support systems, such as improved waste segregation facilities and clearer guidance on proper recycling practices, to bridge the gap between intention and execution. As the review unfolds, the focus will likely shift towards developing more effective and inclusive strategies that align with both local realities and global trends in waste management.
